Anti-US violence could decide White House race
The growing crisis for America across the Arab world is not just a problem for President Obama, but for his rival for the White House, Mitt Romney.
The Republican candidate, who was criticised for attempting to score political points following Tuesday's deadly attack on a US consulate in Benghazi, attempted to draw back from the issue at a rally today.
But he was soon heckled from the crowd for politicising the deaths of the US Ambassador and his staff in Libya.
Both Obama and Romney know that how they respond to the spread of violence in Muslim countries could affect their election hopes.
